I have a string like this "2012.12.04T08:35:00" that represents a time in the "W. Europe Standard Time" timezone.

Now, I want to convert this properly to a c# DateTime object in UTC time.

What is the proper way to do this?

Hi Ankita,

Use TimeZoneInfo when converting between specific time zones:

TimeZoneInfo westInfo =

    TimeZoneInfo.FindSystemTimeZoneById("W. Europe Standard Time");

DateTime westTime = DateTime.Parse("2012.12.04T08:35:00");

DateTime utcTime = TimeZoneInfo.ConvertTimeToUtc(westTime, westInfo);

To address your confusion:

DateTime.Parse as used here makes no assumptions about the timezone of the given value. IT stores it with a DateTimeKind of Unspecified.

TimeZoneInfo.ConvertTimeToUtc as used here expects an Unspecified datetime, reads it as if it is in the explicitly specified time zone, and converts it to UTC.
